PATHOLOGY

Detailed explanation-1: -An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.

Detailed explanation-2: -When two different unit factors are present in a single individual only one unit factor is able to express itself then that unit factor is known as the dominant factor. Another unit factor that fails to express itself is the recessive factor.

Detailed explanation-3: -A dominant trait is a genetic factor that blocks another genetic factor. A recessive trait is a genetic factor that is blocked by the presence of a dominant factor.
